In a study that was published in Cell, Israeli scientists at Tel Aviv University found that when a plant is stressed, its sound intensity rises. It was suggested that this might be one way that plants communicate their unhappiness with their surroundings.
Regarding the 2023 study, Lilach Hadany, the university’s evolutionary biologist, told Science Direct that “Even in a silent environment, there are sounds that humans don’t hear, and those sounds transmit information. Given that some animals are able to perceive these noises, a great deal of auditory communication may be taking place.
It would be extremely undesirable for plants to not employ sound because they constantly engage in communication with insects and other creatures.
Stress causes massive changes in plants, and one of those changes is the presence of powerful scents. They have the ability to alter both color and shape.
But Ms. Hadany’s crew was curious to find out if plants could also produce sound. They studied tomato and tobacco plants under stressful and unstressed conditions to find out more. Plants that were extremely dry or with their stems clipped off would be considered distressed.
